So since new I have been battling this def system. Heater went bad. It’s part of the pump system so I change heater and pump. The nox sensor went bad. I changed the temp sensor because ( I thought) they were reading temp wrong. Wasn’t getting hot enough to regen. Sent me into reduced power mode. Scratch my head didn’t know what else it could be. Found out there is a 9th fuel injector to to dump fuel after turbo to get it hot enough. How does any of this help the environment . It’s mind blowing to me . My 2001 duramax gets way better mpg
